Abstract

The need for energy has now become a major problem that is increasingly complex in all countries in the world to support their economic growth. These various conditions require the need for new renewable energy that can answer these challenges. Wind energy and solar cells have become one of the solutions to reduce dependence on fossil energy. Wind energy and solar energy are actually the most promising sources of energy considering their sustainable nature and very large amounts to be used as electrical energy for lighting in simple people's homes. A wind turbine is a prime mover that utilizes wind energy to drive the turbine blades which are then transformed in the form of mechanical energy to rotate the turbine shaft. Solar energy is energy in the form of light and heat from the sun, which technology can be applied to a variety of energies, including solar thermal electrical energy. New and renewable energy with hybrid or combined systems for home-scale power plants is very much needed to ensure the continuity of the existence of electrical energy and efficiency. The combined and hybrid system models that have been developed and applied are hybrid solar cells and wind turbines.

Abstract

Occupational safety and health are the most important factors in work because they can encourage productivity, which leads to the welfare of all parties, both employers and workers. One way to avoid work accidents and health problems for workers is to use personal protective equipment and production equipment that supports the processing of food and beverage ingredients (coffee beans). Coffee is an agricultural commodity that is used as a raw material for the food and beverage industry. In Kuta Rayat Village, Namanteran District, Karo Regency, there are household businesses and MSMEs roasting coffee beans, consisting of 2 to 3 Small and Medium Enterprises (MSMEs). The process of roasting coffee beans is done manually, so businesses still produce it on a small scale. The roasting process is carried out by roasting tubes that are rotated manually by Mr. Muhammad Iksan Ginting, which can cause harm to the health of business actors as well as roasting results that are not optimal. The roasting process is the process of forming the taste and aroma of coffee beans. If the coffee beans have a uniform size, specific gravity, texture, moisture content, and chemical structure, then the roasting process will be relatively easier to control. The reality is that coffee beans are so different that the roasting process is an art and requires as much skill and experience as consumer demands. Therefore, based on the problems encountered, it is necessary to design tools that can support the product production process. Coffee Roasting Machine With Smart Phone Control System 2kg Capacity.

Abstract

Air pollution due to motor vehicle exhaust emissions is increased. Polluted air harms human health dan the environment. Consequently, it is essential to make a sustained effort to reduce air pollution. The purpose of this research is to investigate the effect of adding aluminum scrap to the exhaust system of a motor vehicle on gas emissions composition. The motor vehicle exhaust system was modified to accommodate aluminum scrap placement. A gas analyzer was utilized to observe exhaust gas composition, such as carbon dioxide, hydrocarbon, and carbon monoxide.  Aluminum scrap with different masses was wrapped around the exhaust's inner tube in 50 gr, 70 gr and 90 gr. The engine speed was maintained at 500 rpm throughout the testing process. It was found that the temperature of the outer exhaust tube is in a range of 40 degrees Celsius to 50 degrees Celsius. The results revealed that the most appropriate amount of aluminum scrap was 90 gr n to reduce carbon monoxide, hydrocarbon, and carbon dioxide in an exhausts gas. The surprising outcome was 76.78 % of carbon monoxide content declined, and furthermore hydrocarbon, and carbon dioxide content were deteriorated by 61.63% and 78.37%, respectively
